Turn Signal Switch Question

[junk4cash]

My 66 has what appears to be the original turn signal switch. I had some issues with the switch canceling but after I took it apart I noticed the previous owner had the hub on in the wrong position so it wasn't tripping the cam. Signals worked fine and then the right signal would only come on every once in a while but left was fine. Now both won't come on but if you hold the turn signal arm up or down with some force, they will work. I mean you really have to put some pressure on the arm. Almost feels like it will break off. I hate to replace the switch. Can I maybe take everything out and clean it? Or does these usually just go out with age? Thanks guys.
